Track quality of experience on Roku
The following instructions provide guidance for implementation across all 2.x SDKs. If you are implementing a 1.x version of the SDK, you can download the 1.x Developers Guides here: Download SDKs.
- Identify when the bitrate changes during media playback, and use the mediaUpdateQoS API to update the QoS info on the Media SDK.QoSObject variables:These variables are only required if you are tracking QoS.VariableDescriptionRequiredbitrateCurrent bitrateYesstartupTimeStartup timeYesfpsFPS valueYesdroppedFramesNumber of dropped framesYesFor example:
bitrate = 200000 fps = 0 droppedFrames = 1 startupTime = 2 qosinfo = adb_media_init_qosinfo(bitrate, startupTime, fps, droppedFrames) ADBMobile().mediaUpdateQoS(qosinfo)
- When playback switches bitrates, call trackEvent(BitrateChange) to notify the Media SDK that the Bitrate changed.
ADBMobile().mediaTrackEvent(ADBMobile().MEDIA_BITRATE_CHANGE)You need to call updateQoSObject with the updated bitrate value.
- When the media player encounters an error, and the error event is available to the player API, use trackError() to capture the error information. (See Overview .)Tracking media player errors will not stop the media tracking session. If the media player error prevents the playback from continuing, make sure that the media tracking session is closed by calling trackSessionEnd() after calling trackError() .
